Last weekend my sister, Angelika, and I took a class in electroforming from Terry Henry. The class was fun and informative.
Electroforming lets you take organic objects and coat them with a layer of copper. This allows you to use natural shapes in metal jewelry. Anything you can find in nature can be incorporated into jewelry. Terry provided many materials including an ammonite, shells, flowers, dichroic glass, micro beads, and beach glass. We chose and assembled them into pendants. We applied special conductive paint and placed them in the acid solution. We were able to pick them up the next day.
This is what they looked like before polishing:
Here is my pendant after I polished it:
